Plasma levels of NT-pro BNP were found to be significantly associated with 393 proteins, after adjusting for sex, race, eGFR and additional covariates found to be significantly different across NT-proBNP tertiles (age, history of stenting, bypass surgery, atrial fibrillation, warfarin use, ACEI/ARB use and BMI, NYHA class; Figure 2A). Here, NPPB is linked to atrial fibrillation.
